Discover how open banking is transforming the financial landscape, giving you more control over your banking data and access to innovative services.
Imagine a world where your banking data works for you, not just your bank. A world where you can easily switch between financial providers, compare products based on your actual spending habits, and access personalised services that truly meet your needs. This isn’t some distant future—it’s the promise of open banking, and it’s already transforming financial services around the globe.
Open banking represents a fundamental shift in how our financial system operates. At its core, it’s about enabling secure data exchange between banks and authorised third-party providers through Application Programming Interfaces (APIs). This means that with your consent, your financial data can be shared safely with services designed to help you better manage your money, find better deals, or streamline your financial life.
The global open banking market exceeded $30 billion in 2024 and is projected to continue growing at an impressive rate of over 25% annually. This explosive growth reflects the transformative potential of this technology, not just for banks and fintech companies, but for everyday consumers and businesses seeking more from their financial relationships.
New Zealand’s approach to open banking differs from many other countries in that it hasn’t been driven by specific regulations. Instead, the industry has pursued a market-led initiative known as Payments NZ API Centre, established in 2018. This collaborative effort between major banks aims to develop standards for APIs to enable secure data sharing while ensuring customer protection.
The development has been steady rather than spectacular, with several banks now offering open banking capabilities through the API Centre framework. ANZ, ASB, BNZ, and Westpac—the country’s major banks—have been working together to implement these standards, although adoption rates remain relatively modest compared to regions with regulatory mandates.
Payments NZ has established API standards covering account information, payment initiation, and customer onboarding, laying the groundwork for innovation. Meanwhile, fintech companies like Akahu have developed platforms that connect consumers’ bank accounts to apps and services, demonstrating the practical applications of open banking principles even in the absence of comprehensive regulation.
Open banking delivers tangible benefits that can significantly improve how we interact with financial services:
For consumers, personalisation becomes the new standard. Banking products can be tailored to your specific needs and processed directly at the point of transaction. Imagine applying for a loan and having your eligibility instantly assessed using your actual transaction history rather than a generic credit score.
The enhanced control over your financial data is equally important. You determine who can access your information and for what purpose, maintaining awareness of how it’s being used. This transparency builds trust while enabling you to leverage your data for better financial outcomes.
Perhaps most exciting are the improved financial insights available through real-time budgeting, saving and investment tools. These tools can analyse your spending patterns across multiple accounts, providing a holistic view of your financial position and actionable recommendations for improvement.
For businesses, particularly small and medium enterprises, open banking streamlines operations by reducing transaction friction. Payment systems can be integrated directly into business processes, minimising administrative overhead and improving cash flow management.
New revenue opportunities emerge as businesses develop specialised services using financial APIs or collaborate with innovative third-party developers. The access to consumer behaviour insights also enables more targeted product offerings and enhanced customer engagement strategies.
Despite its promise, open banking implementation faces several hurdles that must be addressed to achieve its full potential.
Security and privacy concerns naturally top the list. As financial data sharing increases, so does the importance of robust protection measures. Encryption, tokenization, and multifactor authentication must work together with clear data-sharing policies to safeguard sensitive information.
In New Zealand, the absence of specific open banking regulations creates uncertainty for both providers and consumers. While the collaborative industry approach has merits, it may limit the pace of adoption compared to markets where participation is mandated.
Technical infrastructure presents another challenge. Many banks still operate on legacy systems that struggle to integrate with modern APIs. Transitioning to cloud-native architectures and microservices can help modernise these systems, but this requires significant investment and expertise.
Consumer awareness and trust remain crucial barriers to overcome. Many Kiwis remain unaware of open banking’s benefits or harbour concerns about sharing their financial data, even with authorised providers. Educational initiatives and transparent communication about security measures will be essential to build confidence in the ecosystem.
As open banking continues to evolve in New Zealand and globally, we can expect to see increasingly sophisticated services that blend traditional banking with innovative technology. The boundaries between banks, technology companies, and other service providers will continue to blur, creating new models of financial interaction.
We’re likely to see expanded API standardisation beyond basic account information and payments to include lending, investments, insurance, and more. This broader scope will enable comprehensive financial management platforms that provide truly holistic services.
For New Zealand specifically, the question remains whether regulatory involvement will increase to accelerate adoption, or if the market-led approach will prove sufficient to drive innovation. Either way, the transformation of our financial landscape is underway, promising more competitive, accessible, and personalised financial services for all Kiwis.
Open banking isn’t just about technology—it represents a shift toward a more transparent, inclusive, and customer-centric financial ecosystem. By prioritising security, innovation, and customer needs, this revolution can deliver financial services that truly work for everyone.
